1) What is the effect of crossing over in the gametes? What is its effect in the next generation?
2) How would nondisjunction be different if it occurred in anaphase II? Draw the results of nondisjunction in anaphase II for a cell that starts meiosis with four chromosomes.
3) Using the 40X lens, focus on the cells within the pollen sacs in late prophase. Draw a cell in late prophase. Describe any differences from the early prophase slide.
4) Use the 5X lens to observe cells in late prophase. Note that some of our slides show sections of single pollen sacs, not whole anthers.
